Modeling Temperature Effects on Vector-Borne Disease Dynamics
Vector-borne diseases (VBDs) cause significant harm to humans, plants, and animals worldwide. For instance, VBDs are very difficult to manage, as they are governed by complex interactions. VBD transmission depends on the pathogen itself, vector-host movement, and environmental conditions. …

Mathematical models for vector-borne disease: effects of periodic environmental variations.
… a very simple SIS/SIR model for a general vector-borne disease transmission considering constant population sizes over the season, where contact between the host and the vector responsible of the transmission is assumed to occur only during the summer of each year. I discussed two different …

Vector-borne Disease Risk Assessment in Times of Climate Change: The Ecology of Vectors and Pathogens
… in the 21st century will support a spread of disease vectors and vector-borne diseases. Ectothermic arthropods make up the largest group of vectors. They usually cannot self-regulate their body temperatures and are therefore considered to be very sensitive to changing climatic conditions. The …

A Mathematical Study Of Malaria Models Of Ross And Ngwa
Malaria is a vector borne disease that has been plaguing mankind since before recorded history. The disease is carried by three subspecies of mosquitoes Anopheles gambiae, Anopheles arabiensis and Anopheles funestu. These mosquitoes carry one of four type of Plasmodium specifically: P. falciparum, …

Mathematical models and simulations of complex social systems
… Social Systems. The first model represents a vector-borne disease that takes place in a heterogeneous environment composed of areas of different types. Two populations take part in the epidemic process: humans and vectors. The population of humans moves around the heterogeneous environment. …

Simulating the Spread of Malaria: A Cellular Automaton Based Mathematical Model & A Prototype Software Implementation
… of which one-third are of children. Malaria is a vector-borne disease, where a mosquito acts as the vector that transmits the disease. In the last few years, computer simulation based models have been used effectively to study the vector population dynamics and control strategies of vector-borne …

Antibiotic resistant and xenobiotic degrading bacteria that shape the microbiota of the vectors Aedes aegypti & Culicoides sonorensis
Vector-borne disease cases have doubled in the United States over the last two decades. The vectors, Aedes aegypti and Culicoides sonorensis, which transmit pathogens that affect humans and animals, are present in the United States, and their geographic distribution continues to grow. The viruses …

Immune Mediators of Murine Lyme Arthritis
Lyme disease is the most common vector-borne disease in both the United States and Europe; however, its pathogenesis is incompletely understood. The studies described in this thesis aid in the elucidation of mechanisms regulating murine Lyme arthritis and may suggest mechanisms by which human Lyme …

Characterization of the Omega Subunit of Borrelia Burgdorferi’s RNA Polymerase
Lyme disease is the most common vector borne disease in the U.S becoming more frequent where recently the CDC estimated 476,000 cases each year based on insurance records. It is caused by the bacterium Borrelia burgdorferi which is transmitted by lxodes scapularis and lxodes pacificus across the …

Knowledge, Attitudes, and Practices Regarding Tickborne Diseases in Long Island, New York
Most vector-borne disease cases in the USA are transmitted through the bite of ticks. In the Northeast, tickborne infections are a major public health concern and a source of significant morbidity. Human-centric factors that influence tickborne disease risk include the knowledge, attitudes, and …

The Effects of Land Cover Change on the Spatial Distribution of Lyme disease in Northern Virginia Since 2005
Lyme disease has been a growing problem in the United States over the last few decades, and is currently the most common vector-borne disease in the country. This research evaluates the land cover within specified counties of northern Virginia to determine if a correlation exists between forest …

Battle of the Viruses: Aripo Virus Induced Superinfection Exclusion of Mosquito-borne Viruses
… Flaviviruses are transmitted by arthropod vectors, the most common vector being the mosquito. Currently, many mosquito control strategies are in use, these control strategies are diverse in both efficiency and cost. However, developing new vector control strategies is becoming increasingly …

Cost-Effectiveness Analysis Using Agent-Based Modelling: A General Framework with Case Studies
… interest in the use of ABM in human health and disease dynamics. While this is rapidly growing, its application to other relevant areas such as health economics is still in infancy, and frameworks that could systematically apply ABM are still lacking. In this thesis, we develop a general …

Health risk differentials: implications of neighborhood conditions on various health outcomes in New Orleans, 2004-2009
… findings add to a growing body of literature on vector-borne disease risk associated with disasters. The findings of this chapter have a number of important implications for mosquito control programs and supports earlier research findings that vector-borne disease risks increase rapidly …

OspC in the pathogenesis of Borrelia burgdorferi
Lyme disease is a multisystem disorder caused by the tick vector Borrelia burgdorferi. During its life cycle between the tick vector and the mammalian host, Borrelia up- and down-regulates the expression of its surface lipoproteins. Of its many surface lipoproteins, the Outer surface protein C …

Modelling the Transmission of Dengue Fever Based on Spatial and Temporal Patterns
Dengue fever (DF) is a vector-borne disease that has transmit alarmingly in recent decades and has now affected the populations of roughly 100 nations, primarily in tropical and subtropical regions. Approximately 390 million cases of dengue fever are reported each year among people living in 128 …
